The genomic DNA G+C contents of strains LMG 27428T<\/jats:sup> and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified \n \n Streptococcus pleomorphus<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> ATCC 29734T<\/jats:sup>. Strain LMG 27428T<\/jats:sup> could be distinguished from \n \n S. pleomorphus<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> ATCC 29734T<\/jats:sup> based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from \n \n S. pleomorphus<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> ATCC 29734T<\/jats:sup>. The novel genus Faecalicoccus<\/jats:italic> gen. nov. within the family \n \n Erysipelotrichaceae<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> is proposed to accommodate strains LMG 27428T<\/jats:sup> and LMG 27427. Strain LMG 27428T<\/jats:sup> (\u200a=\u200aDSM 26963T<\/jats:sup>) is the type strain of Faecalicoccus acidiformans<\/jats:italic> sp. nov., and strain LMG 27427 (\u200a=\u200aDSM 26962) is a strain of Faecalicoccus pleomorphus<\/jats:italic> comb. nov. (type strain LMG 17756T<\/jats:sup>\u200a=\u200aATCC 29734T<\/jats:sup>\u200a=\u200aDSM 20574T<\/jats:sup>). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus<\/jats:italic> are the generically misclassified \n \n Eubacterium cylindroides<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> DSM 3983T<\/jats:sup> (94.4\u200a% 16S rRNA gene sequence similarity to strain LMG 27428T<\/jats:sup>) and \n \n Eubacterium biforme<\/jats:italic>\n <\/jats:ext-link>\n <\/jats:named-content> DSM 3989T<\/jats:sup> (92.7\u200a% 16S rRNA gene sequence similarity to strain LMG 27428T<\/jats:sup>). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus \n \n Eubacterium<\/jats:italic> \n <\/jats:ext-link>\n <\/jats:named-content>formally as Faecalitalea cylindroides<\/jats:italic> gen. nov., comb. nov. and Holdemanella biformis<\/jats:italic> gen. nov., comb. nov., respectively.
